RRB Signature Size 2026: Resize to 140 × 60 Pixels, 30–49 KB

Railway Recruitment Board forms take your signature as a JPEG of 30 to 50 KB, preferably 140 × 60 pixels or 50 mm × 20 mm, scanned at 100 DPI or more and signed on white paper with a black ink pen in running letters. Upload a photo of your signature below: the tool clears the paper, fits it to 140 × 60 pixels and keeps the file between 30 and 49 KB, just under the 50 KB top, all in your browser.

Why RRB rejects a signature

Capital, block or disjointed letters. The signature must be in running letters; one in capital, block or disjointed letters is rejected.
A signature that does not match. The signature at registration and at the CBT, PET, document verification and medical must match the upload. On a mismatch the candidate may be disqualified, prosecuted and debarred for life from railway recruitment.
Someone else's signature. It must be the applicant's own.
Not centred or cut off. The complete signature should be visible in the centre of its box; the tool centres it with a margin.
Wrong size or format. The form shows an error if the file size or format is not as prescribed.

Sign on plain white paper, photograph it and upload it below. The tool clears the paper, fits the signature to the RRB size under Resize for an exam or job form, and keeps the file inside the KB range. Nothing leaves your device.

Nothing leaves your device

Your signature is drawn, typed and converted in this browser. It is never uploaded and never saved: close the tab and it is gone.

Resize for an exam or job form

Exam and recruitment portals reject a signature outside their size limits. Their notices describe a signature made with a pen on white paper and scanned, so sign on paper, photograph it and use Upload above, then pick your form here. Check the limits against your own notice before you download.

RRB signature: FAQs

What is the signature size for RRB?

The RRB Group D 2026 instructions ask for a JPEG of 30 to 50 KB, preferably 140 × 60 pixels or 50 mm × 20 mm, scanned at 100 DPI or more. This tool keeps the file between 30 and 49 KB.

Can I sign in capital letters for RRB?

No. The instructions ask for running letters and reject a signature in capital, block or disjointed letters.

What if my RRB signature does not match later?

The signature at registration, the CBT, PET, document verification and medical must match the uploaded one. On a mismatch the candidate may be disqualified, prosecuted and debarred for life from recruitments by RRBs and RRCs.

Why does this page keep the file under 49 KB?

The Group D 2026 instructions give 30–50 KB, while guides for some 2025 RRB notices give 30–49 KB. A file between 30 and 49 KB is inside both.

Where these rules come from

The rrb*.gov.in notice pages could not be opened when this page was written, so these rules are the RRB Group D 2026 instructions as reproduced by SATHEE (sathee.iitk.ac.in). Check the notice for your CEN, and use Custom if its limits differ.
